But neither Android nor ChromeOS are self hosting, in the sense that you can't use Android to build Android nor ChromeOS to build ChromeOS (well for the later maybe you could with a Debian container...) So I think traditional Linux distributions will remain, at least as development tools. Of course it is true that many end users these days get by with just a phone or a tablet but this is a general thing and also results in less Windows users too.
